On prevention of persistent seromas after the Liechtenstein operation

The P.V.Mandryka Central Military Clinical Hospital of the Ministry of Defense of the Russian Federation, Moscow, Russia

In order to prevent the formation of long-term seromas after alloplasty of inguinal hernias, we have proposed a method for forming an additional layer capable of absorbing serous fluid. A non-free peritoneal flap is cut out from the wall of the hernial sac, fixed over the implanted mesh, maintaining viability and ensuring rapid absorption of fluid from the periprosthetic space. A positive effect is the absence of direct contact between the mesh and the spermatic cord, which reduces the manifestations of implant-associated inflammation in the tissues of the spermatic cord. This method has received an author’s patent for the invention No. 2636872 dated September 20, 2016. We studied the possibility of preventing seroma by this method in 25 patients in the period from 2017 to 2021 on the day after the operation, serous fluid in the periprosthetic space was noted in 15 (60%) cases, one developed a complication, and the average postoperative bed-day was longer by 1 day.
